For my lower level students I created these morning work sheets to scaffold them to the thousands morning work sheet I also have available on my TPT site.
There is a page for numbers 1-20
100-999 coming soon :)
999+ is already on my site but not attached
-Building/breaking apart numbers
-Mental Math Strategies
For the first pages I have the students draw pictures or dots to group them to see if their number is even or odd. For the last page they use the ones place on the place value chart to group to see if their number is even or odd. You can use however you would like :) I also have an editable version available.
